A Toffoli gate ($C^n$-NOT gate) is regarded as an important unitary gate in
quantum computation, and is simulated by a quantum circuit composed of
$C^2$-NOT gates. This paper presents a quantum circuit with a new
configuration of $C^2$-NOT gates simulating a $C^2m+1$-NOT operation under
the condition $m=2^n$ ($n=1,2,...$). The circuit is composed of units called
multi-qubits gates (MQGs), each of which performs $m$ $C^2$-NOT operations
simultaneously on $3m$ qubits. Simultaneous operations eliminate the need to
manipulate qubits individually, as required in conventional quantum circuits.
The proposed circuit thus represents a more realistic mode of operation for
practical computing systems. A nuclear magnetic resonance implementation of the
circuit is presented as a demonstration of the feasibility of MQG operations
for practical systems.
